ABSTRACT
An attempt has been made to analyze the impact of thermal radiation, activation energy on convection heat transfer flow of a nanofluid in vertical channel with Brownian motion of thermophoresis in the presence of non-uniform heat sources. By employing Runge-Kutta shooting technique the non linear governing equations have been solved. The velocity, the temperature and nanoparticle concentration have been discussion for different parametric variation. It is found that higher the thermal radiation (Rd) larger the velocity, nano-concentration and smaller temperature. Cf enhances with Rd and decays with Nr at ?=?1.Nu enhances at left wall and decays at right wall with increase in Rd and Nr. Sh decays at ?=-1 and grows at ?=+1 with Rd and Nr. Velocity, Temperature decay and nanoparticle concentration grows with increase in E1.Increase in temperature ratio(A) enhances the velocity, nanoparticle concentration and reduces the temperature
